A hydroxyl group is connected to the beta carbon in chemical molecules called beta-hydroxy ethers (the second carbon attached to a functional group).
<h3>If a molecule travels more quickly, what happens to a kinetic energy?</h3>
Because the particles gain kinetic energy as the temperature rises, they move faster, increasing the likelihood of collisions and diffusion.
<h3>Oxygen or hydrogen has more kinetic energy?</h3>
Boltzmann and Maxwell have also researched the gas speed distribution, although this is outside the purview of this course. You may have noticed that for oxygen gas to possess the same mean kinetic energy as hydrogen gas, H2, at the same temperatures, the average speed of each gas must be four times greater.

Explanation:
In Chemistry, one of the ways to test for the purity of a substance is to determine its melting point. Generally, a pure substance has its melting point between the temperature range of 1 - 2 (°C). In order to determine the melting point of a substance, we can use the procedure stated below;
To prepare a sample in a capillary tube for a melting point determination, gently tap the tube into the sample with the open end of the tube down. Continue tapping until the sample is a couple millimeters high. Then, with the closed end of the tube down, tap the sample down slowly or drop the tube into a longer tube. Lastly, you should ensure that you can see some or perhaps all of the sample in the viewfinder (magnifier) when it is placed on the melting point apparatus, then you can turn on the heat.
<em>Additionally, in taking your readings, you should record the temperature for when the melting starts to when it ends. </em>
Answer:
yes
Explanation:
The cell theory states that all biological organisms are composed of cells; cells are the unit of life and all life come from preexisting life. The cell theory is so established today that it forms one of the unifying principles of biology.
Answer:
methanol because it is liquid at room temperature which means that it melts at a lower temperature
